BUTTON.

SPECIFICATION forming part of Letters Patent No.21'8,'767, dated October 25, 1881.

Application {ilcd J'uly 15, 1881.

To all whom it may concern:

Be it known that I, FREDERICK MAAss, of Boston, in the county oi' Suffolk and State-of Massachusetts, have invented certain new and useful Improvements in Buttons for Garments, Ste., of which the following` is aiull, clear, and exact description.

This improved button for garments, as a new article of manufacture, is made of any suita ble hard material-such as bone, ivory, metal, hard vulcanized india-rubber-and in one piece of material, having a convex back and intersecting open holes or passages through the body of such convex back in lines substantially parallel with the face of the button for the passage of the fastening-thread, all substantially as hereinafter described, reference being had to the accompanying plate of drawings, in which- Figure 1 is a face view of the convex back of the button. Fig. 2 is a section in a plane parallel to the front of the button. Fig. 3 is an edge View; and Fig. 4, a section on line xx, Fig. l.

In the drawings, A represents a button. This button A has a convex back, B, and holes or passages a a, running through the thickness ot such convex back in lines substantially parallel with the front O of the button. These passages a a intersect each other within the body of the button, and are open at each end, and from such open ends each continues in a groove, c, to the edge of the button,

the whole making a central shank or hub in one piece with and in the body ofthe button, at and upon the sides of which the said passages a a open and are continued by the grooves in the back tothe edge ot' the button. The passages a a are for receiving the threads by which the button is to be secured in place, and these threads are irst passed though the cloth, thence through one oi' the passages, and again to and fro through the cloth, and thence through the other passage, and so on, and finally fastenedas usual, which secures the button in place.

The button above described is made of one piece ot' material, otA suitablehardness-as, i'or (No model.)

instance, bone, ivory, hard vulcanized indiarubber, metal, Sac.

When the button described is sewed in place the th reads through each hole cross each other, and thus help to give greater security to the fastening; andthe central hub, d, sets the button at its edges oft' from the cloth, and this renders it easy to be buttoned, and also such hub serves to hold and support the button in its proper position and against sagging.

I am aware that the two intersecting passages a a for the passage ot the fasteningthreads, broadly, as applied to buttons, are not new, and such l do not claim; for, as before stated, the peculiarity of my invention consists in forming the button with a convex back, with passages extending through the convex portion from edge to edge of the button, said passages intersecting each other at the center of the convex portion and lying parallel with the face ofthe button.

By this peculiar construction ofthe button it is readily distinguishable from that class of buttons-formed with a central hub or shank having transverse passages for the attachingthread.

It is evident that a button constructed with a convex back and passages therein, said passages extending 'rom edge to edge ofthe button through the convex back, can be more readily sewed in position than a button having a projecting hub with transverse passages; and, further, by my invention the button is so supported by the thread that it cannot hang down when buttoned or unbuttoned, caused by strain and usage, and a guide is formed for the needle from the edge or rim of the button, while a button with a huh or shank presents an objectionable appearance when unbuttoned, the body of the button being at a distance from the material to which it is sewed, and when unhuttoned it hangs down, because it is supported at but a single point-that is, at a point equal in size to the size of the hub or shank.

Having thus described myinvention, whatI claim, and desire to secure by Letters Patent, 1s-

As an improved article ot' manufacture, a In testimony whereofl have hereunto set my 1o button having a flat face and a convex beek, hand in the presence of two subscribing Witwith the interseeting passages a a extending nesses. through the convex body from rim to rini of the button and parallel with its front face,
